|2500||A French spaceship carrying Professor Antelle, his colleague Arthur Levain, and journalist Ulysse Mérou was launched to the star Betelgeuse. Two years passed inside the ship while 350 years passed on Earth.||La Planète des singes|
The French spaceship carrying astronauts Antelle, Levain, and Ulysse crash-lands on an Earth-like planet in orbit around Betelgeuse. They encounter Nova and her tribe of primitive humans. Later they find the planet is dominated by intelligent Apes who capture Ulysee and kill Aurthur while Antele reverts to a primitive state. While a detainee of the apes, Ulysee had sex with Nova. Eventually the apes learned of Ulysee's true nature and accept him into society. Then Ulysse and Nova's son Sirius is born.
